The Kaua’i ‘o’o (Moho braccatus) was a species of bird endemic to the Hawaiian island of Kaua’i. It was a member of the ‘o’o family, a group of honeyeaters native to Hawaii. The Kaua’i ‘o’o was known for its striking appearance, with black plumage and bright yellow markings on its body, wings, and tail feathers. It had a unique and melodious song, which added to its allure.

Tragically, the Kaua’i ‘o’o is now considered extinct. The last confirmed sighting of this bird was in 1987, and despite efforts to search for it, no individuals have been observed since. The primary reasons for its extinction are habitat loss due to deforestation and the introduction of invasive species, particularly mosquitoes and the diseases they carry, which devastated the native bird populations of Hawaii, including the Kaua’i ‘o’o.

The extinction of the Kaua’i ‘o’o, like that of many other Hawaiian bird species, highlights the importance of conservation efforts to protect the unique and fragile ecosystems of the Hawaiian Islands and prevent further extinctions of native species.
